M.A. Introduction to amino acids. Although fructose is a hexose (6 carbon sugar), it generally exists as a 5-member hemiketal ring (a furanose). Learn more. Fructose, or fruit sugar, is a simple monosaccharide found in many plants, where it is often bonded to glucose to form the disaccharide sucrose. Define fructose. Monosaccharides are the monomers from which larger carbohydrates are made. Although all three share the same molecular formula (C 6 H 12 O 6), the arrangement of atoms differs in each case. While fructose and glucose have the same calorific value, the two sugars are metabolized differently in the body. Glycerol Definition Glycerol is a colorless, odorless liquid with a sweet taste.
